Sequestra

sequestra is a Vienna-based climate-tech startup, founded in 2024, that permanently binds CO2 from industrial mineral residues using accelerated carbonation technology (ACT) — the only EU ETS-approved form of carbon capture and utilization. The company combines material analysis, data-driven process optimization, and industrial carbonation plants with in-house monitoring, reporting and verification (MRV) to turn costly waste streams into usable low-carbon construction materials, helping heavy industry reduce disposal costs and generate voluntary or compliance carbon credits.
